Portable Pixelmap Graphic

You can view Portable Pixelmap Graphic (.ppm) files. You can also save files to this format.

The .ppm file format is a simple color graphics format and serves as the lowest common denominator for converting and exchanging graphics files between different platforms. It uses 24-bit per pixel, 8 for red: 8 for blue, and 8 for green. Unlike most graphics file formats, a .ppm file is plain text and can be processed with text processing tools. It is related to the PBM (black and white) and PGM (grayscale) graphics file formats.

This format is mainly available under UNIX and on Intel-based PCs.
